Boot Camp Issues, Help!!

Hey Everybody, I have a issue with boot camp, I have Macbook pro. When I downloaded the Beta version, to install Windows Xp. Everything was going Ok when I was almost done, but i got message that said go to disk Utilitys to format, something along the lines of OS extended Journal. I used my Disk Utility's before to fix another issues with Bootcamp that had me put something in order, I believe one out of 31 was missing. I hope somebody has a clue to help me install a partion to my MAC.
